STEM (Science, Technology, Engineering, and Mathematics) education takes many forms at the Mill School. These include extended long-term projects, such as building a pizza oven or a trebuchet, grafting apple trees or preparing logs for mushroom growing, or creating intricate scale models. They also include shorter-term experimental activities in chemistry, biology, physics, and statistics. 

Students and teachers at the Mill School frequently venture out into the community to seek science and math “in the wild,” through activities like plant identification and examining the frequency of advertising. In addition to these hands-on activities, students also engage in typical classroom lessons, such as lectures, discussions and presentations, creating and interpreting graphs, and recording their thoughts and results in worksheets and journals.
